information technology audit

As stated previously, it is not mandated that information technology audit deploy all 11 classes of the QoS Baseline model; this model is designed to be a forward-looking guide for consideration of the many classes of traffic that have unique QoS requirements. Being aware of this model can help bring about a smooth expansion of QoS policies to support additional applications as future requirements arise. However, at the time of QoS deployment, the organization needs to clearly define how many classes of traffic are required to meet the organizational objectives

This consideration should be tempered with the consideration of how many classes of applications the networking administration team feels comfortable with deploying and supporting. Platform-specific constraints or service-provider constraints also might come into play when arriving at the number of classes of service. At this point, it also would be good to consider a migration strategy to allow the number of classes to be expanded smoothly as information technology audit future needs arise
